Matter melts — if it's 125,000 times hotter than sun

By creating a soup of subatomic particles similar to what the Big Bang produced, scientists have discovered the temperature boundary where ordinary matter dissolves. "Normal matter like we are, nuclear matter, is called hadronic matter. If you excite the system to a very high temperature, normal matter will transform into a different type of matter called quark-gluon plasma," said physicist Nu Xu of the U.S. Department of Energy's Lawrence Berkeley National Laboratory in Berkeley, Calif.
